1-9 = 9 digits
10-99 = 180 digits
So if we continue the pattern to 99, there are 189 digits, and the last 5 digits would be 79899. Counting backwards: 189th = 9, 188th = 9, 187th = 8, 186th = 9, 185th = 7.
The 185th digit is 7.
2t + 5b = 20
8t + 3b = 29
Multiply the first equation by-4
-8t -20b = -80
8t + 3b = 29
-17b = -51
b = 3
Plug 3 in for b into either equation and solve for t.
2t + 5(3) = 20
2t + 15 = 20
2t = 5
Divide both sides by 2
t = 2.50
Arthur must earn $53 in the next week
Answer:
Hence By End of the year with monthly compounded interest it will have 5522.56 $
Step-by-step explanation:
Given:
Initial investment =5.280 $
Rate of interest =4.2%
To Find:
Amount after the 1 year
Solution:
As the investment follows the rule for compound interest as ,
A=P(1+R)^t
Here A=amount after t years
R= rate of interest , P= principal amount t is time period
So given is monthly compounded interest
so t will divided into 12 parts as there 12 months in one year.
P=5280 $ , R=4.2/12 % , t=12

^12

A=5522.56 $
